water closet embodying my invention.

Referring to the drawings-: A designates a hopper or bowtl' andd}, the flush rim thereof.

designates a solhrising seat, which is suitably mounted on a member of the ho per and rovided, in the present-case, wit an which effects the elevation of said seat and retains it in the elestem of t e valve, owi

vated position.

E designates a valve having a head formed-f of or faced-with rubber or other suitable elastic or pliable material, said valve having a stem F which occupies an openin in the. rim B and projects somewhat therrom, so as to be engaged by a limb of an elbow lever- G which is mounted on ears on the rim B and has its otherlimb adapted to be engaged by the sprin H which is connected with the under side 0 the rear ortion of the seat C, so that the descent of tlie latter willo erate the lever G and consequentl the va ve E as will. be hereinafter more ully described. To prevent battering of the stem F or the member inter osed between the seat and said stem should t e seat be thrown down forcibly, the spring H, or H, is employed. The said spring is interposed between the seat stem so that the lever G, or the member G will be. adually brought to act uponthe to the fact that the ht y, and then as the spring first actsli 'it begins its work of spri is c'ompresse .-opera ing the valve stem to its fullest extent,

uses and injuring t whic and thus the valve is closed without abrupt- 'nsequently without liability of parts. q r The rinPB is composed of two walls, the upper portion of the said rim and wal arming a chamber is closed at top and open at bottom. The walls have each an opening forming valve seats opposite to each other, the openbow stem R passing upwardly throu and the flooronwhich the 'hop-.

closed.

.into the pipes M an siderable ing in the the valve E which is adapted to be operated by a leg G or G, .on the seat C as has been stated. The backpf said valve is adapted to close a 'ainst the 'valve seat on said inner wall. he outer face of said valve is adapted to close against the valve seat of the outer wall' of said rim. Connected with saidouter wall at the valve seat thereof is the branch J which with the pipe K which latter is connected with the open flush tank L and opens thereinto. The pipe K is continued below the branch J as at M and extends to the casin N which is below the hopper and wit which is connected ,the primary supply pipe P, said casin also containin the valve 'Q, and seat Q"51eref or, said va ve having its h the top of the casing N is in communication per is supported and having its upper ,end

below'the under side of the seat C and in the path of the'latter in its descent.

S designates a waste pipe which. extends I from the side of the casing N above the valve Q, to the, soil pipe T and is in communication with said casing. and soil ipe for draining said casing when the va veQ is U designates the overflow ipe of the tank L, the same leadin from t e latter to the ho per A into whic it discharges.

e operation is as ticed that the tank L is empty. The seat 0 is occu ied, whereby i lowers and contacting with t. e-stem R, opens -the valve Q. The

lever G- is also operated by said seat, whereb e vali'e E s forced against its seat on t e branch J thus placing said branch and consequently the pipe K out of communication with the hopper. =As water is permi ted to enter the casin N, it flows therefrom K and so reaches the tank L which is thus su plied, I

It will be here notice that. the valve Q, and pipe M are so sized that the filling of the tank slow to allow occupation ofthe seat to a conextent before the overflow of the tank begins'by the pipe-U, this then being direct into the hopper follows; it being no-.

will be accomplished suiliciently -As soon as the seat is vacated, or released,

- seat through which .merely to condition of the yalve the back of the valve closes against said the-ears or axis thereof. This obviates the the valve E 1n the when the water in the branch J will press against the head of the valve E and force it from its outer seat thus opening said valve, whereby the water in the pipe K and the tank L will be forcibly injected into the rim B and so effectively flush the closet, it being noticed that the tank L is empty, consepuently there will be no possibility of reezing said tank, itbeing also noticed that there is no trap, valve ant connected mechanism in said tank and thus there is a maximum simplification of the tank. It will also be seen that whatever water may remain in-the pipe M, when the valve E opens to flush the closet, will enter the casin 'N from whence it will drain into the soil pipe throu h the ipe S by which provision there wil be no reezing of the pipe M and easing N. Furthermore,,owing to the pliable nature of the head of the valve E, when the valve is closed, it will freely leave the back of its seat without sticking and When said valve is open, its head will be forced against and seated upon the inner wall of-said rim. By means of the double faced valveE and the two seats for the same, when the valve leaves the seat which directs water to the bowl, its back closes the opposite the stem F passes and in which it is movable, hence the water fromthe branch J will drain through the open bottom of the-rim and so directl into the bowl. This will prevent the 10 gment of any water about the .stem F, hence there can he no freezing between the back of the valve E and the seat through which its stem passes. Again, as said valve is contained within the flush rim, and as' when the closet is not in use, said va ve is not in contact with water, it will not freeze on its seats in either of its positions.

The following-named features of construction are deemed important: The opening in the inner wall of the flliSh rim serves uide the stem F of the valve E when the atter is opened. In the opened opening to preventany h, .whereby the water bowlever or trip G or'l leakage therethrou will not reach the e necessity of packing said stem. The seat of opposite direction, at the terminal of the branch pipe J, is

.a valve carried by said virtually on i the interior of the bowl, so that said valve trip or lever G has its on the inner an.

.of the flush rim thus utilizing the latter to or lever being support the former, said tri. virtually covered by the bac seat C.

Havin portion of the 5 thus described my invention, what I claim as new and desire to secure'by Letters' Patent, is:

1. In a water closet, the combination with a bowl and a seat of an endwise compressible member outside the flush pipe and depend ing directly from the in front of its hin e, valve stem on the under side of the seat a horizontally-movable owl beneath the seat, and

a lever mounted on the bowl with one armbearing directly against the end of the said stem and the other arm arranged to receive one end of said compressible as the seat is lowered the lever is actuated to move said stem and. said means are compressed.

In a water closet, the combination with a bowland a seat, and a flushing pipe connected with the bowl and having a valve seat, of an endwise compressible member outside of said flushing pipe and depending directly from the under front of its hinge, said. member being compressible at right angles to the direction of movement of the valve 9. horizontally-movablevalve stem on the bowl beneath the seat,

mounted on the bowl the other arm arranged to receive one end of --sa1d compressible means, whereby as the seat is lowered the lever is actuated to move said stem and said means compressed.
